Kencotube is a pioneer manufacturer & trader of Lap Joint Flanges, which is very similar to a slip-on flange, with the main difference being that it has a curved radius at the bore and face to house a lap joint stub-end. Stainless Steel Lap Joint Flanges are characteristically used in circumstances where recurrent dismantling is essential for inspection. Carbon Steel Lap Joint Flanges look very similar to Slip-On flanges but the actual main difference is that the threaded flange has been was bored out to match a specific pipe inside diameter. The back side of the center opening in Alloy Steel Lap Joint Flanges is counter bored to form the appropriate size socket to take the pipe outside diameter.
The diameter of the smaller bore in Alloy 20 Lap Joint Flanges is the same as the inner diameter of the matching pipe. A restriction is built into the bottom of the bore in Duplex Steel Lap Joint Flanges, which sets as a shoulder for the pipe to rest on. Super Duplex Steel Lap Joint Flanges can be used in very high pressure services and their major advantage is that they can be assembled without welding. Monel Lap Joint Flanges itself is not welded or fixed in any way. It is free to spin for proper alignment with whatever it is joining to.The contact surfaces in these Nickel Alloy Lap Joint Flanges do not match and there is no gasket that has one type on one side and another type on the other side.
